PVC membranes
PVC membrane material characteristics:
1.PVC membrane material strength and fire compared with the PTFE has a certain gap, PVC membrane materials useful life in general at 7-15 years. PVC membrane materials in order to solve the problem of self-cleaning, usually at the re-painted PVC coating PVDF (polyvinylidene fluoride resin acid) known as the PVDF membrane material. 
   
  
   photocatalyst several major functional
1, hydrophilic anti-fouling function. Light touch because of oxidation at the surface will produce super-hydrophilic phenomenon, it should not be attached to the surface of stolen goods, resulting in improved anti-fouling nature. At the same time, because of its strong oxidation可氧化the surface of the dirt, it can form self-cleaning coatings, so that was coated surface Forever kept clean state.
2, anti-ultraviolet function. Titania catalyst because of the ultraviolet light absorbent, so that was coated surface from ultraviolet aging effect has been greatly extended the life of James noodle. Photocatalysis using solar energy for photochemical reactions, and the ultraviolet light into energy use, and therefore the function of blocking ultraviolet light.
3, clean-air features. Of harmful substances of atmospheric pollution CO, SO2, NO, hydrocarbons, etc. have strong oxidation, making it a C02 and H2O, so that the total elimination of pollution. In addition, the photocatalyst can release oxygen anion, which returned to the people of a truly green living environment.
